Neutral-Type Time-Delay Systems: Theoretical BackgroundDifferential Equations (ODE). A neutral-type time-delay equation also known as Neutral Functional Differential Equation (NFDE) describes a system in which the rate of change of the state depends not only on the present and past values of the system state but also on the earlier value of the state ra作者: cushion 時間: 2025-3-22 15:08 作者: 吹牛需要藝術(shù) 時間: 2025-3-22 19:25
Ultimate Boundedness Analysistotic or exponential stability in the sense of Lyapunov) can be too restrictive. Namely, the state of a system may be mathematically unstable in some classical sense, but the response oscillates close enough to the equilibrium, to be considered as acceptable.
